Title:
COMMUNICATION CONTROL APPARATUS AND WIRELESS COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/025605
Kind Code:
A1
Abstract:
[Problem] To achieve both the prevention of detrimental interferences and the promptness of power allocations under circumstances where a plurality of secondary systems may be operated. [Solution] Provided is a communication control apparatus comprising: a calculation unit for calculating the to-be-allocated transmission powers of one or more secondary systems that secondarily use frequency channels conserved for a primary system, the to-be-allocated transmission powers including reference transmission powers and further including margins for interference avoidance; and a determination unit for determining a change in the number of secondary systems and for causing the calculation unit to adjust the margins for interference avoidance on the basis of the amount of the determined change.
